SPECIFICATION forming part of Letters Patent No. 528,086, dated October 23, 1894.

Application led December 11l 1893. Serial No.`493,34'7.. (No model.)

To all whom t may concern.-

Beit known that I, CARL FINGER, of Wilkes- Barr, inthe county of Luzerne and State of Pennsylvania, have invented a new and `Improved Steam-Boiler, of which the following `is a full, clear, and exact description.

be fully described hereinafter andl then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure lis a sectional side elevation of the improvement. Fig. 2 is an enlarged transverse section of the same with parts in elevation; and Fig. 3 is an enlarged sectional side elevation of one of the heads.

The improved steam boiler is provided with sets of longitudinally extending and inclined water tubes A, each set being connected at its upper end with ahead B, and at its lower end with a head B, arrangedin the front and rear ends of the brick-work C supporting the boiler.

The heads B and Bf are arranged in pairs, as is plainly indicated in Fig. 2, one pair being located above the other and connected with each other by cross pipes D, and short pipes E at their contacting rims. Any desired number of such sets of pairs of heads may be arranged alongside of each other, as will be readily understood by reference to Fig. 2, in which three sets of such pairs of heads are located alongside ot' each other. The uppermost pair of heads B or B is connected by pipes F or F respectively, or with suitably shaped saddles or branches with the longitudinally extending steam drum G provided with an upwardly extending pipe H supporting a'superheated steam drum I, from which the steam to be used in the engine or other device, is taken. It will be understood that there is a separate steam drum for each set of pairs of heads, as will be seen in Fig. 2.

The lowermost row of heads B or B is supported on transversely extending beams J or J respectively, built in the brick-work, as is plainly shown in Figs. 1 and 2. In the brickwork is arranged the usual tire box K, extending under the uppermost ends of the sets of water tubes A and part of the heads B, as will be readily understood by reference to Fig. 1. i

Each headB or B is made circular inshape, and is provided with a circular rim B2 carrying at its inner end a sheet B3, in which ex` tend the ends of the tubes A of the set belonging to the corresponding head, as shown in Fig. 3. The front end of each rimB2 is provided with a ring B4 riveted to the inside of the said rim and formed with an inwardly extending flange B5 made oblong so as to form a seat for the man-hole cover B6 preferably curved and seated on the inner edge of the liange B5. Each man-hole cover B6 carries one or more bolts B7 extending outward and held `in the usual bridge piece l8 seated against the outer end of` the rim B2. It will be seen that by this arrangement the manhole B6 can be readily removed from its seat on the flange B5, so as to give access to the several tubes entering this head, to permit of expanding the tubes or otherwise repairing the same in case of injury. It will be seen` that by this construction no stays whatever are necessary for the heads B or B', so `that the entire boiler can be constructed from wrought iron, thus rendering the boiler stronger and at the samem time permitting of generating steam to a correspondingly higher pressure.

The lowerinost row of heads B is connected with the usual mud drum L in which the sediment contained in the Water can readily accumulate.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A boiler comprising water tubes arranged in sets, round heads connected to the IOO front and rear ends respectively, of the sets of water tubes, said round heads being ar ranged in sets of pairs, a steam drum connected to each set of pairs of heads, and diagonal cross pipes connected to adjacent heads belonging to the same set of pairs, so that Water and steam can pass from one round head to that located laterally above and connected to the same steam drum, substantially as described.

2. A steam boiler provided with a head comprising a circular rim, a sheet secured to the inner end of the said rim and carrying CARL FINGER.
